Serious problem

At first I thought this was an ok app but soon discovered two problems--one an annoyance and one serious. The annoyance is that it doesn't work at all when you don't have an Internet connection. The serious one is tat it gives the wrong date for Passover 2011 (it says sundown 4/19 when it really starts sundown 4/18). I don't know what other dates may be wrong but the bottom line is I can't trust it, it doesn't really do the one thing it is supposed to. I'm glad I discovered this before planning anything based on the info it gives! Bad info is worse than no info.

Hanukkah Missing even though it shows on app store

The app overall is great, but it's missing Hanukkah. The app even shows it in the screen shot on the app store, but it doesn't show up in the actual app on my phone. What gives?

Love this app

My coworker showed me this great If u are in retail and u don't remember or need to know when holidays are I like it :)
